Title: Big End Gone??? Shurflo
Post by: John Walker on December 04, 2011, 04:17:13 pm

My rather old 100 psi Shurflo runs smoothly most of the time.  Every so often it suddenly makes a rattling noise like it's big-end has failed.  It then runs smoothly again for a time.  It's been doing this for months now and not got any worse but it sounds terminal when it does it.

I've taken the pump chamber off a couple of times and everything looks and feels in good condition.

I'm guessing it's a problem with something loose in the motor section but am wary of taking this apart without advice.

So..... as always - any help appreciated.

John

Thanks - I did wonder about the bushes but it can run quietly and smoothly for ages before going into rattle mode.  When I turn the shaft with the pump housing off it feels quite secure and turns smoothly.

I'm hoping someone can talk me through a strip down to save me messing the whole thing up  ;D

I thought I had a problem with mine, but then realised it was the outlet hose vibrating off the ply liner. It sounded like the pump was running rough.
